Some energy companies I know have their own rooms full of analysts looking into things like what's on TV tonight so they can forecast demand spikes e.g. in the breaks of sports events. They also have data science teams to place their wind farms optimally in-house (my knowledge of the sector is geographically limited to Europe and the midwest of the US).

So make sure that whatever you are getting into is a true need that more than one potential customer actually has, rather than basing things on assumptions alone (customer validation of the proposition).
